nciCntrlSettings fan_run_up_time SNVT_time_sec
0 to 600 seconds
0 0 This configuration variable specifies the time the fan runs before the
outputs are switched ON. It is typically used for electric heat outputs
with fan interlock (see nciFcuConfig.fan_interlock_0 and _1). The
interlock must be set.
nciCntrlSettings fan_overrun_time SNVT_time_sec
0 to 600 seconds
0 0 This configuration variable specifies the time the fan still runs after the
control algorithm has turned OFF the cooling/heating outputs. It is
typically used for electric heat with fan interlock (see
nciFcuConfig.fan_interlock_0 and _1). The interlock must be set. In
case of smoke purge the overrun-time will be ignored.
nciCntrlSettings switch_level_cool[0] SNVT_lev_percent
0 to 100%, 0 = Disable
5% This is the switching level to turn ON stage 1 of the cooling equipment
(if configured as multistage).
nciCntrlSettings switch_level_cool[1] SNVT_lev_percent
0 to 100%, 0 = Disable
50% This is the switching level to turn ON stage 2 of the cooling equipment
(if configured as multistage).
nciCntrlSettings switch_level_cool[2] SNVT_lev_percent
0 to 100%, 0 = Disable
75% This is the switching level to turn ON stage 3 of the cooling equipment
(if configured as multistage).
nciCntrlSettings switch_level_heat[0] SNVT_lev_percent
0 to 100%, 0 = Disable
5% This is the switching level to turn ON stage 1 of the heating equipment
(if configured as multistage).
nciCntrlSettings switch_level_heat[1] SNVT_lev_percent
0 to 100%, 0 = Disable
50% This is the switching level to turn ON stage 2 of the heating equipment
(if configured as multistage).
nciCntrlSettings switch_level_heat[2] SNVT_lev_percent
0 to 100%, 0 = Disable
75% This is the switching level to turn ON stage 3 of the heating equipment
(if configured as multistage).
nciCntrlSettings staging_hysteresis[0] SNVT_lev_percent
0 to 100%
10% This configuration variable applies only to cool outputs configured as
multistage outputs and specifies the hysteresis between switching the
cool stages ON and OFF.
nciCntrlSettings staging_hysteresis[1] SNVT_lev_percent
0 to 100%
10% This configuration variable applies only to heat outputs configured as
multistage outputs and specifies the hysteresis between switching the
heat stages ON and OFF.
nciCntrlSettings reheat_switch_level SNVT_lev_percent
0 to 100%
100% This configuration variable specifies the switch-over control output level
for the reheat output.
